PatentedMay 4, 1909. I

To all whom it may concerni I l Be it known that we, TAYLOR W. HEINT- zELMAN and JAMES G. CAMP, both of Sacramento, in the county of Sacramento and State of California, have jointly invented a certain new'and useful Improvement in Oil- Superheaters for Steam-Boiler Furnaces, of which improvement the following is a specification.

The object of our invention is to provide sim 1e and efficient means whereby oil fuel use in steam boiler furnaces may be heated to the temperature desirable for effective and economical utilization, either in its traverse to the burner, or while contained in the storage tank from which it is supplied thereto, and the supply valve/ and burner maybe readily and completely freed from accumulations of foreign matter tending to impede the free flow of oil to and through the burner, whenever required.

The improvement claimed is hereinafter fully set forth.

It is familiar to operators of oil burning steam boilers, that the oil used as fuel there in should be heated before passing into and through the burner, and also that it is frequently the case, particularly in locomotives operated in cold climates, that the oil becomes thoroughly chilled in the su )ply tank and time is lost in heating it to the proper temperature by the ordinary tank healer. Further, more or less carbon or other foreign matter will often be deposited at or near the discharge nozzle of the burner, and, with heavy crude oil, foreign matter will accumulate around the tank supply valve, the result being, in either case, to impede the llow of oil from the supply tank to the opening of the discharge nozzle, and to correspondingly impair the ell'ective operation of the oil burning appliances emph'iyed.

Our invention is designed to lullil the re quirements and. overcome the objections above indicated, and has, in continued regular service, been found to operate satisfactorily to these ends.

in the accom ianying drawings: Figure 1 is a longitudinal central section through an oil su erheatcr cmlmdying our invention; and, igs. 2 and transverse sections through the same, on the lines (1 a and l; I, 2

respectively, of Fig. I. I

in the practice of our invention, we )l'U- vide a supcrheatcr casing or chest, 1, which is preferably formed of tubing. of proper strength to sustain the pressure of steam carried in the boiler, and is closed, at its ends, by heads, which are inthe form of reducer sockets, 2, 2, in the outer ends of which are fitted and attached in any suitablemanner bushings, 3, 3. An oil sup ly pipe, 4, forming a ortion of the conduit through which oil is lbd from a supply tank to a burner, passes through the bushings, 3; 3, and is made to suitably engage therewith, making steam and oil tight joints, and being secured in position by any suitable means as 5, 5, abutting againstthe outer ends of the bushings. The end of the oil supply pipe, 4, nearer the oil supply tank, is connected to of which another section, 4, of pipe, leadone end of aT fitting, 6, to the central nozzle ing to the oil supply tank, is connected by an v elbow, 7. A steam supply pipe, 8, leading to a connection with the steam space of the boiler and controlled b i any suitable re u,

3 from the steam supply pipe, 8, into the outer end of the T fitting, 6. Said pipe 10 is so arranged as to be in direct line wit 1 oil supply pipc l whereby a direct blast through the supply pipe 4 ma be e'llccted and enabling one by e iening t 10 cock ill to quickly and thoroughly clean out all obstructions that might accumulate in said pipe 4.

in the operation 'of'the appliance, the cut out cock, I], is normally closed, and upon the admission of steam from the boiler to the suppl pipe, 8-, the steam passes into the supcrieater casing, 1, and around the oil supply pipe, l, therein, heating the oil which passes through the pipe, 4-, to the desired temperature, and escaping from the casing through the small vent or discharge opening, 9. in case the oil so )ply pipe, oil tank suppl y valve, or burner should become obstruct cd, they can be quickly and readily blown out, and the obstruction removed, by opening the cut out cock, 1!, and thereby supplying steam directly to the oil supply pi e, through the T 'litting, 6, the firing va ve which controls the supply to the burner be ing closed if the obstruction should be in the oil supply iipc or tank supply valve, or if it should be d esired to heat the oil in the tank;
